This module contains two test interfaces: 

 and 

. The 

and 

Bantam test 

jacks provide intrusive test capability for the incoming E1. By connecting test equipment to these jacks, the 
E1 connection breaks and the test equipment terminates the incoming E1. The 

and 

Bantam 

test jacks provide a bridged access jack for nonintrusive monitoring of the incoming E1. When connected 
to this jack, configure the test equipment for bridged termination.

The Modem Management Network Module provides a single 6-pin modular jack (RJ-11C) (see Table 10 
for the pinout). The Modem Management Network Module provides the following functions:

•

V.34, V.32bis, V.32, V.22, V.23, and V.21 data modulation schemes

•

Connection rates from 2400 to 33.6K baud

•

V.42 LAPM, MNP 2-4, and MNP 10 error correction methods

•

V.42bis and MNP 5 data compression algorithms
